Description

Technical Field

[0001] The invention relates to the technical field of composite materials, and in particular to an acrylic resin composite material and a preparation method thereof. Background Art

[0002] Acrylic resin is a general term for polymers of acrylic acid, methacrylic acid and their derivatives. Thermoplastic acrylic resin has good gloss retention, color retention, water resistance and chemical resistance, and is widely used in the fields of automobiles, electrical appliances, machinery, and construction. However, acrylic resin materials are prone to aging and have low unnotched impact strength.

[0145] Test Case

[0146] Obtain the acrylic resin composite materials in Examples 1 to 5 and Comparative Examples 1 to 3 respectively;

[0147] The tensile strength of the above-mentioned different acrylic resin composite materials was tested according to the method of GB / T 1040.1-2018; then, the above-mentioned different acrylic resin composite materials were aged for 720 hours under 250W ultraviolet light; then, the tensile strength of the composite materials was tested again; the test results are shown in Table 1;
